parse json to object ruby

Question

I looked into different resources and still get confused on how to parse a json format to a custom object, for example

class Resident
  attr_accessor :phone,         


        

Answer 1

If you're using ActiveModel::Serializers::JSON you can just call from_json(json) and your object will be mapped with those values.

class Person
  include ActiveModel::Serializers::JSON

  attr_accessor :name, :age, :awesome

  def attributes=(hash)
    hash.each do |key, value|
      send("#{key}=", value)
    end
  end

  def attributes
    instance_values
  end
end

json = {name: 'bob', age: 22, awesome: true}.to_json
person = Person.new
person.from_json(json) # => #
person.name # => "bob"
person.age # => 22
person.awesome # => true
